Here, try this:
<?php

$filename = 'numbers.txt';

$handle = fopen($filename, 'w+');
 

if (is_writable($filename)) {

	$start = microtime();

	for ($i=1;$i<=1000000;$i++) {

		fwrite($handle,$i."\r\n");

	}

	$end = microtime();

}

else {

	die('File does not have write permissions');

}
 

echo 'Completed. Process took: '.($end-$start).' seconds';

?>
